(first of all sorry for my bad english) (i searched both TB and web for this subject but couldnt find an answer) does anybody know if the movement of outside of a paper cone is "exactly" same as the movement of its center ? i thought that maybe at high volumes while the center perfectly obeys the signal coming from amplifier but the outer parts may not be the same like the center of it, because it is made of paper and it can "bend" somehow ? and if so: is it the result of a large diameter speaker's (like 18, 15 inches) sound to be more muddy when compared to smaller ones like 12 and 10 inch speakers ? also: is the design philosophy of aluminum cones are perfect moving cones that does not bend so the outer and the center moves exactly the same to give a more detailed sound ? Thanks.
